  • Patent number: 9493817
    Abstract: A method for decomposing a target nucleic acid polymer, comprising: bonding a probe nucleic acid polymer and a microparticle to form a probe nucleic acid polymer-bonded microparticle, adding a target nucleic acid polymer to the probe nucleic acid polymer contained within the probe nucleic acid polymer-bonded microparticle to form an addition microparticle, and energizing the microparticle contained within the addition microparticle into a high-energy state and then using energy transfer from this high-energy state microparticle to decompose the target nucleic acid polymer.
    Type: Grant
    Filed: March 5, 2007
    Date of Patent: November 15, 2016
    Assignee: Genesis Research Institute, Inc.

  • Patent number: 9109297
    Abstract: A method for producing an accumulated product of a nano-substance that enables the accumulated product of the nano-substance to be produced at low cost, by a simple process that requires few conditions to be controlled and requires minimal energy, and with good reproducibility. Specifically, a method for producing an accumulated product of a nano-substance, the method including crystallizing a protein in a state where the protein and the nano-substance co-exist within a solvent, thereby accumulating the nano-substance within pores of the protein crystals to obtain the accumulated product of the nano-substance.

  • Patent number: 8986510
    Abstract: It is intended to provide a method whereby a target to be analyzed can be easily decomposed in a micro region and a decomposition apparatus. In the decomposition method of decomposing the target to be analyzed and the decomposition apparatus, the target is allowed to coexist with a microparticle and then the microparticle is put into the high-energy state. Then, the target located in the vicinity of the surface of the microparticle is decomposed due to the energy transfer from the high-energy microparticle toward the target. Thus, the target can be easily decomposed in a micro region.
